CIRCUIT-BREAKER TERMINAL.

Specification of Letters Patent.

Patented Feb. 24, 1920.

Application led October 16, 1918, Serial No. 258,476. Renewed January 17, 1920. Serial No. 352,243.

To all whom t may concern:

Be it known that I, GEORGE N. FREY, a citizenv of the United States, residing at Pasadena, in the county of Los Angeles, State of California, have invented certain new and useful Improvements in Circuit- IBreaker Terminals, of which the following is a speciication.

My invention relates primarily to a circuit breaker terminal for use in the overhead power lines of electric railways and has for its object the provision of means for easily and quickly positioning the end of the Wire therein and which Will positively retain the same in its position of use thus obviating the possibility of accident through the wire becoming accidentally loosened.

A further object is to provide a device of that character which, when used in a continuous transmission or supply line of electric railways, will connect or form a continuation of the trolley wire thereby minimizing the danger of the trolley wheel of the car leaving the wire while making the crossing.

Other objects and advantages will appear hereinafter and while I have shown and will describe my preferred form of my device it will be understood that I do not limit myself to such preferred form but that various changes and adaptations may be made therein without departing from the spirit of my invention.

In the drawings accompanying and .forming a part of this application:

Figure 1 is a side elevation of my device in its position of use.

Fig. 2 is asectional view, partly in elevation, of one end of my device, on an enlarged scale.

Fig. 3 is a bottom plan of Fig. 2.

Referring to the drawings 5 is a rectangular block or base of wood or other suitable material provided at each end with cut-away or recessed portions 6 and 7, and a groove 8 in its central portion.

Extending longitudinally and centrally of the recessed portions 6 and 7 are grooves or sockets 9 and 10, best shown in Fig. 2.

My wire holder comprises a base plate 11 of a thickness to substantially fill the recesses 6 and 7 and of a width and length corresponding to the dimensions of the said recesses, which base plate is secured positioned to block 5 by means of bolts 12. As both of my wire holders are of the same construction only one will be described herein. Secured to the underside of base plate 11 by bolts 13 and 14 is a body member 15, tubular in transverse cross-section, which is provided with upwardly extending bosses 16 and 17 of a length to properly space said body member from the base plate.

Extending centrally and longitudinally through body member 15 is a chamber 18 in which the end of the wire 19 is received. The upper portion of the rear end of body member 15 is cut away to form an eXtension of chamber 18 and a recess 20 is cut in plate 11 in register therewith for a purpose hereafter explained. A set screw 21 in the upper side of body member 15 serves to hold the wire against displacement. Mountf ed in the groove 8 is a downwardly projecting spacing or bridging member 22 which serves to bridge the space between the ends Y of the wires for the passage of the trolley wheel, and is of fiber or other suitable insulating material.

In the use of my device the wire holders will first be removed from the block 5. The end of the wire will then be passed through chamber 18 until the end projects a suitable distance beyond the rear end of body member 15. It will then be bent upwardly and then forwardly to lie upon the upper face of plate 11. The set screw 2l will then be tightened and the wire holder repositioned upon block 5. Suitable means will be provided for securing bridge member 22 in its position of use.

Having described my invention what I claim is:

A circuit breaker terminal comprising a rectangular block; a recessed portion at each end of said block; a groove extending longitudinally and centrally of each of said recessed portions; a groove extending longitudinally and centrally of said block between said recessed portions; and a wire holder mounted in each of said recessed in the recessed portion oi said block; and a portions each Comprising a base plate bridge member mounted in the groove be- 10 adapted to be mounted in said recessed tween said recessed portions. portion; a body member secured to said In Witness that I claim the foregoing I base plate to extend parallel With Said have hereunto subscribed my name this 20 block; a longitudinally extending chamber day of September 1918.

in said body member; a connection from the rear end of said chamber to the groove GEGRGE N. FREY.
